FULL PRODUCT INFORMATION

Precision, easy-to-load grips for a wide range of tensile and fatigue applications

Series 647 All-Temperature Grips provide all the advantages of our popular Series 647 Hydraulic Wedge Grips in a design that can be operated within an environmental chamber at temperatures up to 1000°F (540°C). Two models are available: one with a range from –130 to 315°C (–200°F to +600°F), and the other from –130 to 540°C (–200°F to +1000°F). These grips are opened and closed remotely, so there is no need to cool them down before changing specimens. Rapid specimen changeover can be accomplished without touching the hot gripping device. In addition, because the grip head operates within the chamber—at test temperatures— thermal gradients between the grip and specimen are minimized. When these grips are used within an MTS environmental chamber, gradients as low as ±3°F (1.6°C) can be achieved.

As with all MTS hydraulic grips, these provide a constant, adjustable gripping force, regardless of the test loads applied. This consistency prevents specimen slippage or damage to soft specimens during testing. When actuated, all moving parts of the grips are hydraulically locked in place so the specimen can be cycled from full tension to full compression without backlash.

Wedges for these grips are available in many configurations for testing both flat and round specimens. To minimize potential damage to your specimen shaft, you can order our flat wedges with an optional Surfalloy™ finish. This rough, tungsten carbide surface coating provides firm gripping of even the most brittle composites to deliver more accurate, repeatable material characterization.

FULL PRODUCT INFORMATION

Wedges for Series 647 Wedge Grips come in a variety of surfaces to meet requirements. They employ a unique wedge design that significantly reduces the stress concentration on the specimen, enabling even very brittle composites to be gripped securely without grip-induced failure.

MTS 647 Wedges can be ordered with a water-cooled option. These wedges are used with a Water Cooling Kit that is purchased separately.

Model 647 All-Temperature Wedges are available for the all-temperature grips. Contact MTS for additional information.

Water Cooling Kit

There are two versions of the Water Cooling Kit. Both versions include hoses, fittings, metering valves and a manifold that attaches magnetically to your load frame or other flat, steel surface. One version also includes water flow switches. Some MTS products, such as the Model 653 furnace, support integration with the flow switches, enabling protection of the equipment in the event of a water supply failure. Please check with an MTS Applications Engineer to determine if your equipment is compatible with the flow switch protection circuit.

KEY PRODUCT FEATURES

Easy Specimen Insertion

Side-loading lets you quickly and easily insert specimens

Excellent Repeatability

Clamp onto your specimen in the same position, test after test, to minimize the bending strains that can invalidate your test results

Adjustable Pressure

Hydraulic pressure can be adjusted, allowing these grips to be used for testing a variety of materials

Multiple Wedge Selection

A wide variety of wedges are available to meet your testing requirements

FULL PRODUCT INFORMATION

Precision, easy-to-load grips for a wide range of tensile and fatigue applications

Test after test, MTS 647 Side-Loading Hydraulic Wedge Grips clamp your specimen in exactly the same way for consistent, repeatable testing results.  Their superior alignment and constant, lateral gripping force minimize the bending strains, vertical loading forces and slippage that can invalidate test results and cost you time.  The hydraulic pressure to these grips is supplied by an external grip supply and is adjustable. This allows the grips to be used for testing a variety of materials, including plastics and ceramics. An adjustable gripping force prevents damage to your specimens from grip or specimen slippage during your tests.

 

Your specimens are also protected by the 647’s preload chamber which locks all moving grip parts in position, eliminating backlash when cycling between tension and compression. These grips can be mounted on non-hydraulic frames when used with an optional, stand-alone hydraulic pump and valve assembly. They can also be mounted in environmental chambers when equipped with optional, high temperature hydraulic fluid and seals.  A variety of wedges are available for the 647 grips and are sold separately. These grips are also available in axial-torsional models.

TECHNICAL OVERVIEW

The MTS Model 685.53 Grip Control Unit accurately controls pressure to hydraulic grips. Each grip can be actuated independently. The kit includes the grip control unit, hydraulic hoses to the hydraulic power supply, hydraulic hoses to the grips, and a universal mounting bracket. The control unit requires 21 MPa (3,000 psi) input pressure and can control the pressure to the grips from 0.7 MPa to 20 MPa (100 psi to 3,000) psi with a resolution of ±0.07 MPa (±10 psi). This range and resolution allow the user to select the proper grip pressure so it holds the specimen sufficiently without damaging it. The stability of the controlled pressure is ±0.5 MPa (±25 psi) yielding no extraneous load fluctuations within your test. The clamping speed of the grips is also adjustable.

TECHNICAL OVERVIEW

Model 685.22 & Model 685.10 Stand Alone Hydraulic Grip Supplies

The 685.22 and 685.10 units feature a self-contained hydraulic pump, a 0.75 kW (1 hp) electric motor, a 11.3 l (3 gal) reservoir, a 10-micron absolute return line filter, and hoses for connection to grips. These units are furnished with individual directional control valves for upper and lower grips. The grip supplies use a special hydraulic fluid which allows the grips to be used in environmental chambers at elevated temperatures. They are designed to run continuously, which results in good pressure stability and easy adjustment of the output pressure. Grip closure rate is also adjustable. Since the grip supplies are self-contained systems, they allow the use of hydraulic grips on non-hydraulic test systems.

Model 685.60 Hydraulic Grip Intensifier

The 685.60 Hydraulic Grip Intensifier, which utilizes an innovative fluid-to-fluid intensification system, is used with grips that require a pressure higher than the normal system hydraulic pressure. Two versions are available with factory adjusted output pressures of 45 MPa (6,500 psi) and 69 MPa (10,000 psi). The output pressure is adjustable from 10 MPa (1,500 psi) up to the grip supply output rating. To minimize the set-up time of larger grips, a high volume upgrade kit is available

 Standard Features Include:

  • Directional control valve for each grip
  • Center valve detent, allowing unparalleled control of over gripping
  • Continuous positive pressure design, providing high pressure stability over the entire operating range
  • Separate flow control valve for control of grip engagement speed
  • Independent grip circuits eliminate crosstalk
  • Easy to maintain and service
  • Accommodate a wide range of electrical connections

TECHNICAL OVERVIEW

The MTS Series 646 Collet Grips offer the best value of any fatigue testing grips available. The design of the Series 646 Grips allows for excellent repeatability from one specimen to the next, minimizing bending strains. Loading is simply a matter of sliding the specimen into the smooth collet. There are no expensive threads or button ends to machine and no additional bolts or collars to install. The Series 646 Grips were designed primarily for round specimens. A special high temperature collet package is available for the 646.10 that utilizes the extension rods supplied with our Model 680 High Temperature Grips. This package will provide you with the same high-temperature capabilities as the 680 grips, and requires the same specimen adapters.

TECHNICAL OVERVIEW

Model 680 High-Temperature Grips were expressly designed for high-temperature, low-cycle fatigue testing, but can also be used for other types of tension-compression or tension-only testing. The grip heads and extension rods are constructed of high-temperature, super alloys selected to extend into the heated zone of the furnace, minimizing the thermal gradients within the specimen. Accessories for these grips include a hand pump (required), your choice of buttonhead or threaded specimen adapters, and a water cooling kit.
